I had no problems installing this beta release on my test server. No hickups, no errors, the whole installation and post-logins worked just fine.

Didn't test anything else but looking in admin I can't see anything new from 4.4.5. I guess most of the improvements are in the background and how XC works which is hopefully improved. I did see some bugs I reported long time ago finally being fixed in this release (they were not in 4.4.4 or 4.4.5) so this is also an improvement. Most items from the list in the first post and some other improvements / bug fixes will probably make this a good upgrade release - hopefully there will be 4.4.x-4.5.x full upgrade not just database.
